WIRE-GLASS MAGHINE.

Application filed March 15, 1927. Serial No. it'5,550.

This invention relates to the manufacture of glass and has specialreference to a ma-- chine for making the so-called wire glass whereinWire is embedded in the glass to 5 prevent the accidental breakingthereof.

@ne important object of the invention is to improve the generalconstruction of machines of this character. 7

A second important object of the invenno tion is to provide an improvedarrangement of pressing rolls in machines of this character.

A third important object of the invention is to so arrange the pressingrolls in such it a machine as to provide special thickness along thelines Where the wire is inserted.

A fourth important object of the invention is to provide improved meansfor holding the wire during the forward movement 30 of the traveling bedcommon in such machines.

A fifth important object of the invention is to provide no rovedmeansfor cutting ofi the wire upon t e completion of each sheet as ct class.

with the above and other objects in view as will be hereinafter ap arentthe invention consists in general certain novel details of constructionand combinations of parts hereinafter fully described, illustrated inthe accompanying drawings and specifically claimed.

in the accompanying drawings like charactors of reference indicate likeparts in the several views, and:

Figure 9 is an enlarged detail view showng one manner of adjusting theroll bearings.

Figure-10 is an enlarged detail showing the motor drive for theinvention.

In the embodiment of the invention here shown there is provided a air ofside frames 10 which are prefers 1y made in sections secured togetherthough these side frames may be made integral if desired. Between theseside frames is arranged a pair of rails 11 whereon run track wheels 12carryin an axle 13 which is journaled 1n hanger earings 14 supportedfrom the underside of a carriage 15. This carriage is of general troughshape and seated in the trough of the carriage is a bed plate 16 whichis adjustable tor height by the adjusting screws 17 This bed late isprovided with a series of longitudinal passages 18 communicating at eachend with a header 19 so that connections 20 may lie-made for coolingwater. Thus the water is admitted at one end of the bed plate and drawnoff at the other.

At each side of the carriage body is a rack 21 and one of these racks isengaged by a gear 22 on a reversible motor 23 supported on a base 24:.By this means the bed plate and carriage are driven to and fro on therails 11. On each or" the frames 10 there is provided a pair of bearingstands 25 wherein are mounted vertically slidable bearing boxes 26 whichmay be adjusted for height by means of the wedges 27 carrying screws 28each of which extends through a respective stand and has on it a nut 29,movement of the nut drawing the wedge in one direction or permitting itto move in the opposite direction. Also, on top of each box is a. spring30 the tension of which is adjusted by a reguiating screw 31 providedwith the usual hand wheel. The hearings on one side of the machine arearranged opposite the bearings and in one set of these hearings isjournaled a cylinder 32 having a spaced series of grooves 33 extendingthere around. in the other set or: hearings there is a cylin der 3tjonrnaled and cyiinder is pro vided with a spaced series of ribs 35corresponding in spacing and position with the grooves 33. The outeredge of each I'll) 35 1s grooved to engage the wire W. At each side ofthe machine the bearing stands support a vertical frame 36 and at thetop of this frame is journaled a pair of rollers 37 between which thewires are fed from one or more reels of wire, not shown. Beneath therolls 37 is a fixed shear plate 38 having.

therein inverted frusto-conical openings 39 which are spaced to lie inthe planes of the grooves 33 and ribs 35; The frame 36 also supportscross bars 40 whereon restsa movable shear blade 41 having openings 42therein which normally register with the openings 39 in the plate 38.Springs 43 normal y hold the movable plate 1n pos1- tion for thisalinement by a lever 44 pivoted as at 45 which extends down along sideof the, carriage so that when the carriage is at the end of its movementthis lever is engaged by a lug 46 and rocked on the plvot to move theblade 41 and thus cut oil the wires which are fed downward between therolls 37. Below the shear the frame 36 supports guide tubes 47 whichextend down close to the bed 16 so that the wires are conducted to theirproper positions. Each of the rolls 32 and 34 is provided on each endwith a gear 48 which meshes with the respective rack 21 so that as thebed is reciprocated the rolls will rotate and it is to be noted that thegears and rolls are so proportioned that no slipping of the wire orglass occurs during the movement of the bed.

It will be seen that there has been here shown a very few of the guidetubes and shear openings but it is intended that these tubes andopenings shall be spaced about two inches, center to center,.and thatthe rolls shall be about seventy-two inches long though I'am notconfined to these dimensions. However, for clearness in illustration thetubeshave been reduced in number and shown as of larger size, inproportion to the other parts, than is actually intended. ll may,therefore, use as many tubes as l: desire and also can space them toobtain the most eflicient results.

Toward the delivery end of the machine there is a further pair of?bearing stands tQ supporting bearings 50 pressed downward by springs 51having their tension regulated by hand screws 52. in the bearing 50 isjournaled a flattened roll 53.

At one end of the carriage there is a recess 54 wherein is mounted anelectro-magnet 55 the core of which extends from one side of the bed tothe other is about level with the top of the bed though it may be alittle below. At any rate, it is not in position to be engaged by thehot glass. This electromagnet has its winding connected to form asuitable source of energy, not shown, and is so wound that it issufliciently strong to hold the wires W when they are fed down and restthereon.

A suitable ladle L is provided at the receiving end of'the machine forpouring the glass onto the table.

In operation the hot plastic glass 1s poured on the table and the motorstarted. The glass then is rolled out by the roll 32 into a sheet Shaving ribs R and as it passes beneath the guide tubes the wires, whichhave been engaged by the magnet, rest on these ribs so that as the sheetS passes beneath the roll 34 the ribs 35 engage these wires and forcethem into the glass as shown in Figure 3*. The glass then passes beneaththe roll 53 and the grooves made by the ribs 35 are closed by the actionof this roll. When the bed has moved to nearly the end of its stroke thewires are cut oil and upon completion of the sheet it may be removed inthe usual manner.

There has thus been provided a simple and efiicient device of the kinddescribed and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction of the invention without departing from the material spiritthereof. It is not, therefore, desired toconfine the invention to theexact form herein shown and described, but it is desired to include allsuch as properly come within the scope claimed.

Having thus described the invention. what 15 claimed as new, is:
